Huygens' final descent towards Titan started at 1013 GMT and is planned to land on the moon at around 1234GMT. During the descending process, it will film Titan's surface, measure wind speed and pressure and analyze the atmosphere as it descends to the surface.

The mission of the European built space probe Huygens on Titan is "a scientific success," announced Friday Jean-Jacques Dordain, general director of the European Space Agency (ESA). (Photo: Xinhua/AFP)

This is one of the first raw, or unprocessed, images from the European Space Agency's Huygens probe as it descended to Saturn's moon Titan January 14, 2005 and released, January 14, 2005. It was taken from an altitude of 16.2 kilometers with a resolution of approximately 40 meters per pixel. It apparently shows short, stubby drainage channels leading to a shoreline. It was taken with the Descent Imager/Spectral Radiometer, one of two NASA instruments on the probe. (Photo: Xinhua/Reuters)
